ARRI Introduces New Large Format Alexa Mini LF
ARRI combines its Alexa LF sensor with its Alexa Mini body with the new Alexa Mini LF.

Since releasing its Alexa LF camera just over a year ago, ARRI has found a way to turn heads once again with the unveiling of its new Alexa Mini LF, a combination of two cameras in one compact offering with ARRi's large format sensor placed inside the popular Alexa Mini body.
This is big news for ARRI fans and filmmakers looking for the best of both worlds. “Large format, small camera,” as ARRI bills it, the new Alexa Mini LF will feature Netflix-approved UHD up to 60fps and lower noise with higher usable sensitivity.
Here’s everything you need to know about ARRI’s new Alexa Mini LF.
ARRI Alexa Mini LF
Let’s start with the sensor. ARRI reports that the Alexa Mini LF will use the same A2X sensor from the Alexa LF, which is slightly larger than full frame at 36.7mm x 25.54mm. The Alexa LF Mini will include three different sensor models, listed below.
- LF Open Gate: 36.70 x 25.54 mm with (4448 x 3096) at 44.71mm image circle
- LF 16:9: 31.68 x 1782 mm with (3840 x 2160) at 36.35mm image circle
- LF 2.39:1: 36.70 x 15.31 mm with (4448 x 1856 photo sites) at 39.76 mm image circle
The LF Open Gate being the optimal pixel size, while the LF 16:9 will maximize lens options at 4K and max 60fps recording and the LF 2:39:1 being the cinematic widescreen option. The El values are between 160-3200 with true 800 ASA sensitivity.
Recording Capabilities
- 4.5K in LF Open Gate and LF 2.39:1
- UHD in LF 16:9
- 2K 16:9 with in-camera downscale in LF 16:9
- HD 16:9 with in-camera downscale in LF 16:9
The Alexa Mini LF should have about the same exposure latitude as the Alexa AF with 14+ stops, but with less noise and better skin tones.
